Last year, the Google Science Fair became the largest online science fair in the world with over 7,500 entries from more than 90 countries. Some key changes to this year’s fair, designed to make it even more global, include:

A “Science in Action” award, sponsored by Scientific American -- for a project that addresses a social, environmental or health issue to make a practical difference in the lives of a group or community

All projects are submitted entirely online. Submissions are open today through April 1. Visit www.google.com/sciencefair for more information.
